Saving Custom Score Templates

Firstly, I apologize if this has been asked before--I looked through several pages of this forum without seeing a similar topic. I've also looked through the various menus in the program itself, but I didn't see anything that looked useful.

My question is this: Is there a way to save a custom score template that will show when MuseScore first opens? I use similar instrumentation for a lot of my pieces, but it gets old having to add and remove instruments from the score template every time I want to start writing something. It seems that it would be a lot quicker to save the template(s) I use most often--especially since MS sometimes crashes when I try to edit the instrument list.

Any help will be appreciated.
