Want more than 5 options for a custom field value

[pembeguru]

Each custom form field has spaces for 5 options ("If you are using radio or dropmenu custom form fields, you can specify the options below.")

Can I have more than 5 options in the registration form if I add additional rows in the appropriate table in Admin.cgi?
Or do I need to do something else in addition to adding rows?
Or is 5 options the limit?

For a particular application, I want 20 options.

I have the full version of Locked Area, Version 6.4

For example, if I want 6 options in Field 1, I would add:
[code]<tr><td><font face="Arial" size="2"><span class="gen"><b>
Option 6
</b></span></font></td><td><font face="Arial" size="2"><span class="gen">
<input type="text" name="cfg_custom_field1_option6" size=30 value="$config_vals{custom_field1_option6}"$dropmenu1_disabled>
</span></font></td></tr>[/code]
