Two trill auxiliary note questions

Good morning, Dorico-verse,

Here are my two quetions:

  1. I feel that the right-hand paren is too close to the trill auxiliary note, unless that note has a ledger line. Is there any way for me to modify that?
  2. I am working on a score which is asking for a LOWER auxiliary note for a trill (i.e. a primary note of B-natural and an aux note of B-flat). Does Dorico have an option for a lower aux note? My workaround has been to write it as a tremolo, but it looks weird when the part above it also has a trill for the same duration with an upper aux note.

Grateful as always for your thoughts.

For context, here is a picture that shows the OP’s point (1):


I agree that the RHside parentheses is too close. Not sure the user can do something about it.

For point (2), you can select a negative interval in the Properties Panel:


This brings up another issue where the parentheses collide with the ledger line. Not even in Engrave Mode I’ve found any option to help with this.
