show only specific samples in genomic evolution chart

[inodb]

On the evolution chart:

https://www.cbioportal.org/patient/genomicEvolution?studyId=lgg_ucsf_2014&caseId=P04

Add a new button to show only specific samples. Can look same as current group by:

But instead it says "Select Samples: All", and then the dropdown gives you different samples to include/exclude (checkbox style)

Just to clarify, from the example you've provided, there are 80 different samples. If this were to be done, I'm guessing there would be around 80 checkboxes? I'm assuming the size of the dropdown would still be the same which should be doable.
