You could perhaps do this with code, so it is only one C-c C-c? Alternatively, 
is OrgAggregate useful? https://github.com/tbanel/orgaggregate

Here is a hack to filter clock entries by tag:

https://lists.gnu.org/archive/html/emacs-orgmode//2009-09/msg00205.html

Finally, the Clock Table documentation 
https://orgmode.org/manual/The-clock-table.html mentions ‘:match’ with link to 
https://orgmode.org/manual/Matching-tags-and-properties.html#Matching-tags-and-properties
 which lets you do negative matches in one of their examples. Can you include 
only relevant tags, or exclude the tags you want to exclude using that syntax?

  -k.
