Test Step Analysis/Step chart - specifying run more dynamically

We would like to be able to specify run by multiselect checkboxes, in the dropdown menu, as highlighted in the green box in the image.

Even more so, if we could specify run number ourselves, instead of the predefined options.

This would allow us a higher degree of freedom, when we want to compare a lot of charts.

Furthermore, if possible, we would also like to have the possibility to select specific runs per UUT in the left sidepane.

If we could expand the UUT, to check specific runs, by expanding the UUT, like you expand the test step (as depicted by green arrow)
