Suppliers and material

The assignment of the supplier to the material does not make sense for us, it would be good if the dependency were reversed.
Then the material consumption could also be recorded on the APP without first having to search for a supplier, to which the correct materials must also be assigned beforehand.

With the large number of suppliers who deliver the same materials, it would be better to first select the material and then see who could deliver it to me, especially since the supplier closest to the construction site can then also be displayed.
Or the supplier can be omitted for the pure material certificate.

Important: Material must also be able to be created on a construction site basis, at least it should be possible to pre-assign material groups / individual materials from the global master for the project or even to assign them to a TEAM.
