Unable to reset the build counter for a shared build number

[wrankmore]

We have the requirement to refresh the build counter, of the shared build number, on a daily basis.

We use the format '{d}-b{0}' with a date format of 'yyDDD'. As such we have a unique build number for the day. However, although you say in the docs that 'it is recommended not to reduce the counter', it actually stops you from doing it.

I would like to reset each day change, e.g. 17179-b12 (being 12 builds on this day), would then change to 17180-b1 for the first build of the next day.

Is there an API call I could run to reset a particular value?

I know I could script something to update the XML file on the server but would rather not.
