How can you use Common Metrics in Custom Expression?

I have prepared indirect calculations in Common Metrics and I would like to be able to use them in Custom Expression.

Hi @malt
That’s currently not possible (0.32.8) and I cannot find any feature request for this. I would recommend that you search and if you don’t find any other issue, then create a new issue.
And please post a link here after - just for reference.
