Thanks for getting in touch! You are unfortunately correct that this is not currently a support feature. The suggestion from Dalmiro in the post you linked is a handy workaround to get an AND to work, but the OR is still not possible.
The subject comes up internally every now and then but itās not something we have decided to commit to yet. I think the UserVoice suggestion is going to be the best option for this right now.
If you have any further thoughts or questions on this, please let me know.
