Feature request: taggable trackers

[froyglez]

There are some things I only do during certain days. For example, I have the "Walking" tracker in the "Health" group and the "Wash the bathroom" in the "Housework" group. I do both activities on saturdays. Also, in those groups I have activities that I don't do on saturdays. I would like to have the ability of creating tags, for example, a tag for every day of the week so that I can only visualize the trackers of the corresponding day. Thanks in advance!
