Editor Utility Widgets Feedback

Hi, i’d like to make buttons to set light map resolution via editor widget but the only exposed parameters is “get light map reslution” and there is no “set”…
I try to use recorsive “compute lightmap density” till it reach the correct value but it’s not the right way to achive my goal (and also it’s a very wrong way of doing things…).

It will be usefull to have expose at least all the parameters in the details rollout and not only some of them…
