Option for general height of slurs (ties)

Dear Forum,
I’m using MuseScore 2.0.3 on Windows 7.
In some scores I prefer slurs and ties which don’t curve so much. Please could you integrate an option to affect the general height of slurs (ties)? In Style > General > Slurs/Ties there are only options to thickness and minimum length. As the curve depends on the several factors that must be something like a percent-value.
