Non-consecutive date preests in Vizlib Calendar

I'm looking to set up a preset range for Vizlib Calendar that would allow selection of non-consecutive periods - for example, LYTD + YTD, or January, April, July, and October of this year (the first month of each quarter).

I can write these as Qlik formulas in the search bar and save them as a bookmark, but in Vizlib Calendar I haven't been able to find any way to allow this to be written as a quick-select date range. My preference would be to have this within the calendar if possible.

If there's any suggestions as to how to achieve this, I'd love to know!
