Drumine Notation and Sound Issues

Hello everyone! I have come across a couple of problems while using the marching percussion instruments in Musescore 2. Here at the few that I have found. Most of which have to do with the tenor drums.

 1.  When notating drum 4 for tenors, the sound is not created when you use the playback feature. 
 2.  For tenors, drum 3 sounds like a drum 4, drum 2 sounds like drum 1, and the drum 1 sound has no differentiation between itself and the spock drum sound. There are only 3 separate drum sounds. Last time I checked, Tenors usually have 4 drums with 1 or two spock drums.   
 3. The rim shots for tenors.  Rim shots sound like rim clicks, not rim shots.  This is a very difficult issue for me because I cannot hear the sound of the specific rim shot on tenors that I want to hear. I need to hear what I am writing for me to be completely sure of the part that I am composing.
 4.  There is no notation for a crossover for tenor drums. 
 5.  There is no notation for rolls on any percussion instrument. Rolls are extremely common in the percussion society.  You need rolls.  Not just for drums, but for marimba and other keyboards as well. 
 6.  There is no diddle notation for any drum.  This causes inefficiency when trying to create fast passages.  I find myself having to notate the exact note value then writing in every. single. sticking.... 
 7.  Percussion composition should just be easier.  I applaud the effort that has already been put into this application.  It is very easy to use and can be learned fairly swiftly.  However, I feel that there has been some neglect towards the percussion side. 

 Below is attached a new marching indoor percussion show that I am writing.  Some of the issues I have addressed can be seen below.  For example, the marimba in the opening statement with tied dotted half notes is meant to be a sustained roll.  Adding a trill is not what I want.  Also towards the end of the excerpt there is a drum feature.  Look how I have to notate the exact not values rather than the actual diddles. Annoying....  Also notice how certain drums in the tenors sound the same and some do not even have a sound.  

 In conclusion, I would appreciate with any of these issues if you are aware of how to fix any of them.  Any help with this would be greatly appreciated.  Thank you!
