Assigning and Changing Names in BRT

Hi all

I was wondering if anyone knew whether it was possible to change the assigned names of an alignment.

I have an existing alignment which has been created with 34 surveyed points.

I import the exiting alignment from the survey into my .alg file.

I now assign names to each surveyed point, the problem is that if I start with 5000, then my last surveyed point will be 5033.

But for reasons I wont go into sometimes the surveyed points need to be assigned names that increment by every 5 or 10 or 20 etc such as 5000, 5005, 5010, 5015...

Is there anyway of assigning names so that each name is assigned a value based on some interval such as 5 or 10 etc.

If this is not possible how can I manually change the assigned names?

Thanks
