Hi @lostdruid Currently, this is not possible. All you can do is give employees advance notification (either via texts or Team Messaging) of blackout dates and then if they request time off for one of those, you can deny that request.
If you want to, you can head to the Ideate Board and submit a feature request. That will start an evaluation process for a future product roadmap. If you do this, please post a link to that request here. I, for one, will definitely support that request as a fellow seller.
