There is an per-instrument setting for articulations, embeded in the instrument's definition.
Only very (very very) few instruments make use of it, the vast majority used the global defaults.

Like this:

        <Articulation>
          <velocity>100</velocity>
          <gateTime>100</gateTime>
          </Articulation>
        <Articulation name="staccatissimo">
          <velocity>100</velocity>
          <gateTime>33</gateTime>
          </Articulation>
        <Articulation name="staccato">
          <velocity>100</velocity>
          <gateTime>50</gateTime>
          </Articulation>
        <Articulation name="portato">
          <velocity>100</velocity>
          <gateTime>67</gateTime>
          </Articulation>
        <Articulation name="tenuto">
          <velocity>100</velocity>
          <gateTime>100</gateTime>
          </Articulation>
        <Articulation name="marcato">
          <velocity>120</velocity>
          <gateTime>67</gateTime>
          </Articulation>
        <Articulation name="sforzato">
          <velocity>150</velocity>
          <gateTime>100</gateTime>
          </Articulation>
        <Articulation name="sforzatoStaccato">
          <velocity>150</velocity>
          <gateTime>50</gateTime>
          </Articulation>
        <Articulation name="marcatoStaccato">
          <velocity>120</velocity>
          <gateTime>50</gateTime>
          </Articulation>
        <Articulation name="marcatoTenuto">
          <velocity>120</velocity>
          <gateTime>100</gateTime>
          </Articulation>

I'm not able to manipulate that.
Would a plugin be able to do this?

It would be useful if any application could also act on a selected group rather than individually.

You'd need to edit the mscx file

Well, thanks. That's a solution that gives control. Do you have to do each note individually or can you do a group?

That'd be per instrument

you can use light accent or marcato as other options.

I'll try that thanks.

EDIT: I looked up marcato and it seems that it is actually louder than an accent. Do you have any more information?

Marcato means different things in the classical and jazz worlds. To most classical musicians, it means louder than a standard accent but the same length. To most jazz musicians, it means shorter than a standard accent but the same volume. It's a relatively uncommon marking in the classical world, so the MuseScore default is the jazz interpretation.
