@FuzboleroXV Generally, you are proposing to group with the same meaning. These hashtags could be different forms of the same word, abbreviations, different spellings, including spellings in different languages; and even synonyms. Actions with the will be like shortcuts for each in the group. E.g. tagging, subscribing or viewing.
?!
I expect that some users would like to group hashtags differently, so these groups will be user-defined.
