Thanks a lot for your suggestion. The problem that you face is clear. As it was fairly mentioned by hhamedk there are no ''global'' presets in Wialon and the ones that we have work in regards of a element-user combination which means that editing a preset will make changes for a particular user and the corresponding elements they have access to, not all the element-user combinations that are linked to this preset.
As I see it, the assignment of presets is used for basic setup which means that if then there is a necessity to make changes in access rights for a particular element-user combination, the changes are made outside the preset. Not in the preset itself. That's how I can also explain myself why there are no requests like this one from other partners.
All changes in ACL logic are painful as a lot of staff is already linked to it, so no immediate actions will be taken, but anyway, I will note down the problem that you mentioned and keep an eye on it.
It would be great if other partners also comment on this topic and describe in more details how they use the presets and whether they experience the same kind of inconvenience.
