Build Agent VCS deletion police

Hi,

I have noticed that, when no build configuration associated to a certain VCS run on a while (like in two weeks), its checkout in TeamCity/BuildAgent/work gets deleted.

This is giving us some troubles, since our build depends on some hand made previous configuration that we have to perform after we download the code for the first time, and said configuration can't get uploaded to the source control.

Whenever our VCS checkout gets deleted and the build configuration hast to download it completely from the VCS, our builds fail and we have to re-aply said configuration.

Is there any way to change that deletion policy to prevent it?

Thanks in advance.
