Trial period reset without extension

Is there any way for me to reset the trial period automatically when I release a new build? I am going to beta on my product and I will not have access to the individual members of the beta pool to supply 'one on one' trial extensions. I understand that I can bundle a new .dat file in the application with a longer trial period but that would mean that there were versions 'out in the wild' with excessive trial periods, especially if the beta runs for more than a few months.

No, you have to release a trial extension to these users.

Or you could embed a trial extension in your app (or installer) and apply it programmatically.

Thanks. I understand why it works this way. I'd rather not embed extensions. I'll see if I can go any other route with the beta site. Thanks again.
