Hello. Can I remove old package versions and other builds? On the example of Icecat:

    252.1 MiB [          ] /5ym67s5vp1vmnc3y4ds4r3687vc3nl25-icecat-52.6.0-gnu1
    252.0 MiB [          ] /360i9ca4gnm3rsjj8v43ih0j3mfrp40n-icecat-52.6.0-gnu1
    246.8 MiB [          ] /kd0nnq3i0qarx4vqxcampxfj3igxn84h-icecat-52.3.0-gnu1

(Or is it possible to remove a specific package, in "package-version" format?)

And the next question, is also about Icecat: version 52.6.0 was compiled from source. This is too long. Can I create binary package from this local installation?

If possible, please give a couple of examples.
