OIR - Numbering Logic

Hi Guys,

I want to know if we can merge the attribute values to create a single attribute.

For example, I created a WT part. 

I filled out the attribute number 8989, created and added the customer number attribute in WT, and selected it from the drop-down list. I also manually entered the project number for one more attribute. Everything I get into the Number attribute. Is it possible to do it through OIR?

Regards,

Aj
