Is it possible to change buddypress group forum permalink structure?
Like : example.com/groups/sample-group/forum/topic/%post_id%/
last part will be %post_id%, instead of /%post_name%/.

The default structure is creating problem in some languages. I used Persian to the topics name. Link looks like:

I am using the latest versions of WP, BP, bbPress
I tested these plugins:

• bbPress Permalinks with ID
• Custom Post Type Permalinks

both work correctly in forums that are not associated to a buddypress group, the link is like:
[sitename]/forums/topic/[topic-id]/
but when forums are associated to a group, the link is like:
[sitename]/groups/[group-name]/forum/topic/[topic-name]/

I found the same question in this topic, with no reply:
