How to change MQTT tags path?

Hello team,
Currently I am working on Ignition Edge [trial version] related to MQTT concepts.[Have installed MQTT related modules also]

I am using a 3rd party[MQTT.FX] application for Publishing the Topics.
By Default when the topic is published it gets stored under MQTT Engine path..

How can i change the Publish path to other location [say edge]

Reason why i wanted to change the path from MQTT engine to edge:
Under MQTT engine path: There is no option for exporting the Tags which are created.
[the export option is disabled]

Same Tag if its under edge Path , i have option to export the tag.

Can anyone provide a solution for this!!!!

Please don't double post.
