Filter options on a contact's timeline

My use case is to write topics/questions that I wish to discuss with my contacts when meeting them next time. I made a few event types dedicated to future interactions but found it time-consuming and irritating to scroll through the whole timeline to see what I wrote when hanging out.

It would be helpful to have a filter by event type to quickly view what I have prepared and then change the event type after the discussion so that the entry doesn't show up in the result next time. And if I could set a default filter for timeline with a contact on Dex mobile app, it would be golden. Imagine when meeting someone, I could open Dex, find the contact, then read a timeline by a default filter without the need to set a new filter manually, then edit the event detail and type after the discussion.

By default, it's like a to-do list, but I can see notes from past interactions when turning off the filter.
