System object positions

I would like rehearsal marks above the top stave only, but other system objects above the top stave and another stave lower down. I realise this isn’t currently possible. Trying to get round it, the only way I can find to omit the lower rehearsal mark is to drag it off the page, and I wonder if this might be storing up problems for later. Is there a better way of hiding it, or some more cunning workaround entirely? Many thanks.

For what it is worth, I have just done exactly what you describe, yesterday, with system text. I don’t really like how undoricoish it feels and hope that some better options will be available in the future!
