In my master page I have:

```
MembershipUser thisUser = Membership.GetUser();
loggedInUserID = thisUser.ProviderUserKey.ToString();

```

`thisUser` gives me access to all the fields in `aspnet_Membership`.

I want a new field, `isSubscribed` for each user. I can use an SQL query to fetch the value fine, but I want to know if there is someway to modify the membershipuser object so it retrieves this value as well, so it is accessible from:

```
thisUser.isSubscribed.ToString();

```

Thanks for any help!
