Ability to change hairpin open end height if hairpin is long/short

Hello,
As i am on the hairpin code, why not add a grip to adjust the opening?
I also noticed that when the hairpin is short opening seem too large, it could be automated depending on the size of hairpin. Two levels seems sufficient, as in Sibelius.
But in this case it would be better to add an opening userOffet to keep the automated reduction in all case. What do you think about this?
