Someone else might have a different idea, but for that I think I would make a different rollable table (or alter the one you have). For instance, the 2-5 result would have 4 entries and the 6-10 would have 5, because weights won't matter once it is made a token. Create a token from the rollable table and scale it up on the VTT to where everything is easy for you and your players to read. Use the choose random side from the right click menu to make rolls. There might be a way to choose random side with Tokenmod also, but I've never needed that function to see if it exists.
