Filter on expertise's resource

Hi,

I have many resource and one resource have many expertise but, in projeqtor, I can't register that.

So, i found i can register many function for 1 resource, a main function and plenty of resource cost.

The problem is, i can't filter on resource cost on the resource page for select the resource i want to use, even in custom filter popup.

How i can filter on resource cost ? If i can't, how i can register skills on 1 resource ?

Thanks for the future answer.
