Yes, there is. see https://tiddlywiki.com/#Dominant%20Append
By default, items in a list are "dominantly appended", which automatically
"de-duplicate" the results, so that individual items will appear only once
in the resulting list
Of course, as you have discovered, this is not appropriate when using math
operators. To work around this, you can use the "=" prefix in front of
each filter run, like this:
{{{ =[title[$here$]get[vashi.$mynow$]] =[title[$here$]get[vaslo.$mynow$]] =[
title[$here$]get[disabil.$mynow$]] +[sum[]] }}}
