How to organise Posts within channels

Hi,

Hoping that someone could share some thoughts and/or advice in relation to a scenario we're trying to find a solution for.

We have a channel, in which we use Posts to share information, which can be grouped into two or three themes, with channel members. For clarity, please refer to the below pic for what I mean when referring to Posts (as distinct/different functionality from chats).

What we'd like to do is mark the posts, with the respective theme, and be able to filter the theme so that users don't need to scroll through the whole list to manually find posts related to the theme they'd like to see.

Some other considerations:

• we like the idea of using a consolidated channel for multiple themes, so that there are less different channels etc that users need to navigate/keep across
• all channel members need to have access all posts (not any specific subset of members/users)
• if there was a way to have multiple "Posts" tabs, this would work for us to be able to share the themed posts to a centralised posts space, as then users could access the separate Posts tab for specific themes as/if required
• we're trying to find the least "clunky" solution/approach to achieve an ease of grouping/finding posts related to a specific theme

Thanks in advance for your time and thoughts : -)

Cam.
