Hi Eliott, Nour, I have added the function to support one use case. Could you PTAL? For the use case of combined input of sweep and parameterized circuit, will be added in the followup PR. Let's first make sure this PR is in the right place and do the right job. Thanks!

I tested it a little bit in this colab, and it doesn't seem to work properly yet, the interface looks good to me.

Thanks so much @babacry!!! I tested it here, and it seems to work!

One small comment: it would be nice if the merged single-qubit gates ended up in the same moment; see this cell of the colab.

Got you, thanks a lot for the manual checks! I will update the pr accordingly and fix checks.
