Hi lewisgrantevans,
if you want to use the time picker, you cannot use lookups, did you explored the choice of summary indexes?
they are indexes with timestamp and all the fields you have in lookup, in other words they are lookups with a timestamp, they are very quick and don't consume license.
So you can schedule a search (the same that populates your lookup) and write results in a summary index adding as last row | collect index=my_summary .
Then you can search on this summary index.
Bye.
Giuseppe
