RewriteRule, Redirect 301, htaccess and Openlitespeed

#1
So I tried using Redirect 301 in htaccess, but it didn't work (and it seems that it's not possible to use it with OLS), then I noticed that RewriteRule does work, but there's a problem:
It only works if I place it before "# BEGIN LSCACHE" rules.
I'm worried, if I keep it in the beginning of my htacess, will I lose my changes on the next wordpress ols plugin update or due to some program changes or settings?
