I posted a mod (not approved yet), but I did not add a link to a support topic, and there seems no way to edit it now.
https://custom.simplemachines.org/mods/index.php?mod=4221
https://custom.simplemachines.org/mods/index.php?action=postmod;sa=edit;mod=4221 does not work for you?
Does not provide a field to input support topic ID.
The topic is not created until the mod is approved.
And the topic is automatically created
