Add "Don't display in parts" and "Don't Display in full score" option for texts

When I'm editing a conductor score, I need to place multiple tempo markings and rehearsal marks in both on top of the woodwind sections, the brass section, the percussion, etc. It's fine for me to do it manually until I start editing the parts. I have to hide every redundant text in again and again and it's a pain in the butt.
I know I can fake them with staff texts but it's still a tiring work. Plus, too many hidden objects on screen makes it difficult for ones to focus on the layout of scores. So a function to make them completely invisible would help a lot.

Apart from tempo and rehearsal marks, conductor's note is also supposed not to be shown in parts, and conversely, sometime it is not necessary for notes on parts to be on the conductor's score, too. A good example might be the end of " Lincolnshire Posy". On the condensed score, there's a conductor note about "Tp. and Bar. should not arrive at the last note at the same time", whereas on part scores, the note is basically "Don't follow the conductor here".
