Change accidental tone

Greeting,

I write Arabic music. In Arabic music, we use half flat and half sharp. I don't have an issue with half sharp, but the half flat symbol used in Arabic music is different than MuseScore. I circled the notes in the attachment that I need to change its tone from the measure below to the notes in the measure above it?

I mean, I want to make the tone of (b with cross line) like the tone of (b with small arrow above it).

Regards,
