Patching Relevance Help

I’ve put this together to get a list of months that an endpoint has OS patches for

unique values of (month of it as two digits) of (source release date of it | date "01 Jan 1970") of relevant fixlets whose (name of site of it contains "Patches for RHEL 8" and category of it does not contain "Support" and fixlet flag of it) of bes computers whose (name of it = "xxxxxx")

Is there an easy way to combine the sum of download sizes in GB beside each month?

e.g.

01 = 0.46 GB
02 = 2.1 GB
