Built-In Scheduling Calendar Request

I often find it's difficult to know who among my friends in various Discord servers is available to play when I'm available.  It can involve sending lots of DM's to invite friends to play trying to coordinate things to find times that align with each other.  A feature that I would love to see is shared calendars built into Discord.  The idea would be that people could show the times they are expecting to be available for gaming for upcoming days/weeks and then list the games they are interesting playing during those times.  Their friends could also share their calendars and see their friends' calendars to quickly see when their friends are available.  Ideally, this could span multiple Discord servers (i.e. you pick either the friends you want to share the calendar with and/or you choose to share the calendar with everyone on specific Discord servers where you are a member).  For example, then I could quickly see that on Tuesday night when I'm planning to be available Joe, Jack, and Sarah are also planning to be free for gaming during those times and they want to play the same games as me.  That would help me quickly narrow down who plans to be available the same times as me increasing the likelihood that I can get some games in with friends and it would help me plan out my gaming times for the week ahead of time.  There are also many times where I'm available, but might just be watching TV or something, and the shared calendar would let other people know that I'm available if they want to play so they can just send me a DM without needing to "cross their fingers" trying to guess which friends might be open to playing games at that time.  I think this feature would significantly increase the likelihood of coordinating times available to play games with willing friends.
