if you have an existing post that you want to show in a different channel, you can edit the message and cross-post. This will add the top-level post to the different channel, but will not include the full set of replies. We will keep this request in mind as we evolve the cross-posting feature in the future and update if the status changes.
Details on cross posting can be found here: https://support.office.com/article/cross-post-a-channel-conversation-in-teams-9c1252a3-67ef-498e-a7c1-dd7147b3d295.

Please add this capability as soon as possible. Posts can quickly mushroom out of control with content that really belongs in another Channel. Lack of this ability seriously limits usability and adoption of Teams in a corporate environment. One can't always perfectly plan ahead for all the Teams and Channels that will be needed. Even with the right arrangement, people, myself included, frequently post to a channel that may not be the most appropriate.
