Molto cresc/dim, poco a poco markings etc

I would love if Musescore can include (in the lines palette) not just cresc or dim in written form, but also:

molto cresc,
molto dim,
poco cresc,
poco dim,
poco a poco cresc,
poco a poco dim

Also tempi related associations, like:
poco accel.
poco a poco accel.
poco rall.
poco a poco rall.

These are used a lot in orchestral and chamber music, and at the moment, all I can seem to do is add these as italics text and drag down to align with the only two existing options, which is neither aesthetic nor functionally optimal. Over many years, no update as yet has included it which is weird considering its oft use. Maybe because it is difficult to align with playback?... but I wouldn't really mind if it doesn't correlate to that at all (great though if it could)... I would just love it to be there as an italic expression mark in the default palette for ease of use (have tried to add it myself through the 'more' tab, but doesn't seem to allow).
