Custom field search

Hello guys, we have a custom type post, with one meta field for each day, and the schedules times for each post-day. For example, the post id =23, has on the meta_key “sunday_time” the value “00:30,01:30”. Then another row for same post id and same meta_key, but with the value “22:30,23:30”. And then another row, same post id , but with different meta_key : “monday_time”.. and so on..

The filter i d like to apply is a dropdown, or list of checks, with the week days and if you select one (for example Monday) it filter all the posts that has at least one row with meta_key for that day (for example “monday_time”). I dont care to filter by time, but i need to filter by posts scheduled for a certain day.

How can i make that with Search & Filter Pro ? (i have the license).
