Create shared folder in a custom location

Hello,
How can I create shared folder with a specific location? I do not see option to select location while creating shared folder.
Alternatively how to change location in existing shared folder? Path field in shared folder properties is grayed out.

TS-464 Firmware version: QuTS hero h5.2.4.3079

Shared folders on QuTS are created directly on the pool space and cannot be moved around

The screenshot shows a default used system folder (homes) that cannot be changed/renamed
