Extension for auto assign certain component to same size groups

HI all.
I have a lot of boards in my framewalls of my house, but they are auto generated by Housebuilder extension. Wall consists of the same size boards.

I want to make a cut list, but all of them are groups.
I found an extension that calculates number of components.
Is there a way to “optimize” model, so that all same size groups (figures) become instances of 1 component, but not 1000 different groups?

Update: Ok, I found the suolution its the “component replacer” extension. You choose all groups that yu want to convert to a sinle component and it works.
