Feature: Exclude events by regex

[dreamflasher]

Goal: Blocking times in my work Outlook calendar from my private calendar but not syncing the blocks back.

Details: 1) I use Outlook for work and want my private appointments to be marked as "not available" (but not share all event details) and 2) I want my work appointments to show up in my google calendar. (1) is easily be set up with syncing Google Private Calendar → Outlook, but when setting up the 2nd sync for (2) to sync Outlook → Google Work Calendar, all the blocked events will end up in Google Work Calendar, which is undesirable. What I would need to achieve this is to have a regex filter to exclude events with a certain title.
