Is it possible to have scheduled saved search using summary indexing and dynamic token depending on user query?

[splunkreal]

Hello,
one user wants to convert dashboard with token to summary indexing dashboard.
We are using | sistats or similar, scheduling data collection each minute or other frequency.

However user has token input to filter later dynamically search results.

Is it possible to have scheduled saved search using summary indexing and dynamic token depending on user query?

May I remove the filter and grab all results then filter in the final summary indexing dashboard?

Thanks for your help.
