Approach to share Content between channels

Hi there,

We have two channels ch1 & ch2. Have setup appropriate security domains for ch1 & ch2 users [author/editor] to access only ch1 & ch2 channels and content folders respectively which is working fine.

Now, we have a requirement wherein the ch2 users wants read access to ch1 content so as to use them on their channel. We tried granting readonly role on ch1 content folders for ch2 users which enabled them to see ch1 content, but they can’t use them on ch2 channel components as brXM seems to display content folders based on channel mapping (probably via /hst:hst/hst:sites/regional). Is there a way to choose ch1 (channel) content for ch2 channel ? Alternativley, are there any (known) approaches for this scenario ? Thanks!
