ERROR : Cannot select parent warehouse while creating a new POS Profile

[Chintan_Diwakar]

HI there

I want to create a POS Profile for my Shop in which there are 4 selfs. I want to sell all the product in the shop in a single POS item list, which I am unable to do as I cannot select parent warehouse in the warehouse dropdown while creating POS Profile.

Here is my warehouse tree →
Main Store
- shelf1
-shelf2
-shelf3
-shelf4

Attaching the screenshot as well here.

Is this the default behaviour or I am missing out something?

Unable to find solution for this, Ideally parent warehouse should also be displayed as a single shelf can also be considered as a warehouse.
