customizing the web.config file (work around might be needed ??)

can i produce a text file that has the infomation for the tag <allow>

so a user can edit the text file and the web.config reads that file to get the data??

line in the web.config file:

Code:

---

<authorization>
  <allow roles="Server001\AdminGroup, Server001\ViewerGroup, Server001\ModGroup" />
  <deny users="*" />
</authorization>

---

please help if you have any ideas, or work arounds?
thanks,
tom
