Question

Hello.
In order not to produce the same type of custom fields, I will ask if it is possible to do this?
The following custom fields have been added for the trading infoblock site directory s1

How to add them for the trade infoblock site directory s2?

Answer 1

It is impossible, not provided, at the base level, the OneToOne connection. Binding to only one entity.
It is possible to do it differently, on the vskidka one user field with a binding to the element and transfer the general settings all to this element.
