NUMBERING X- FOLIO (Sheet)

Welcome.

I test numbering cables on project and i present problem:

I numbering cable format X:FOLIO.

Solution works prfectly but when i go to other FOLIO and example come back to the previus edited FOLIO the numbering start from 1.

1:3
2:3
3:3

Hen i edit other folio and come back to the 3 folio

1:3
2:3
3:3

Not
4:3
5:3
 etc.

I think to add to each folio "database" with actual numbering values for cables , elements tec. Then when come back to edited folios nubering its ok. And when each folio or project have this database file its no problem to make solution for correct numbering values when object was moved or deleted.

Sorry for my English.

Best regards.
