Limiting access to products attribute for Salesman group

[recorad]

Hi,
hope u do well in france.
I've a simple question. Is there any possibility in prestashop to limit access to a product attribute like Pre-tax wholesale price or special offers for a group.
we have several groups who should input this various attributes to a products.
Alltough I was directed to the prestashop userguide by the friendly addons support guy, I couln't find any preferneces to do so.
Is there any addon or php workaround to achive the goal?

 

I'd be glad to get some help!
best regards from Austria!
