New field type named "Number Pro"
Similar to Espocrm Number field (auto increment) but you can make it incremental in groups
You can pull the prefix from a linked entity varchar field
You can specify an int field on the linked entity to hold the counter indicator
There is separator param, optional with pad length like in Number field
Use Case
On of the most use cases is the order and order items, so if the order has number field you can add number pro to the order item that prefixed by the number of the order
So if Order number is: O-00046
The Order item number will be: O-00046-0001
