[Feature Request] saveable filter sets

[jdion84]

you can current save a filter set, however i think it would be sweet if you can save multiple different filter sets and give them names. this would be useful for cases where several different types of reports are done on a regular basis.

if there is interest, i could submit a PR for this. we could still use the same localStorage implementation, but instead of it dumping 1 set, it could have a group of objects instead, with a name/key attributed to each
