Muse Sounds - Muse Choir Playback

Going through MuseScore 4 I do love the new Muse Sounds-- but composing for mostly Choral stuff, I find myself stuck with a few things that need to be looked at. I know it probably isn't remotely close to top priority but I thought it should be further mentioned (If it hasn't been mentioned already):

-Choir is extremely too soft, I have my SATB voices on max faders at 12, a Piano at 0, and Master at 0... piano still overpowers and I still need to crank up my computer's volume to as high as it can go to hear piano-- let alone, pianissimo
-Choir doesn't seem to follow certain notations, like staccato, marcato, etc.
-Choir makes ends or transitions of almost everything into a legato when no slurs exist between measures or in measures

***While unrelated... an Option for Ooos and Ahhs like MS Basic would be a nice feature

At the time being, I know I can use Muse Sounds Strings (which sound gorgeous by the way-- put a number of my VSTs to shame) or MS Basic sounds... but MS Basic doesn't follow dynamics (like forte-piano) and Strings can't properly convey some vocal things (plus, also has the legato ending--- but for whatever reason, works nicely for strings at the moment.
