Multiple Counters on same Table

Could somebody provide text field based counter script where we can use multiple counters on same table please?

MVD has a counter component but it can only be used 1 instance of it on each table.

Counter script I'm looking for does followings:
- It has prefix and unique count numbers. They can be defined in script as to what prefix letters will be used and at what number it starts counting.
- When a record is deleted, it reverts back to last used number and starts counting from there. i.e If record containing SI-10 count text value is deleted, it will start counting from SI-9, therefore new record number will be SI-10.
- Each counter is independent to each other so that multiple counters can be used on same table.
