ReadOnly -- Form and Group

Setting the entire form, or group to READONLY.

Currently, I have 2 options:
[1] set each field readonly -- field by field -- in the Rules section. To be fair, I can include upto 15 fields, and then copy the rule to cover the rest of the 100+ fields,
- OR -
[2] create a task form, which requires additional customization and is extremely time consuming.

My suggestion: -- under Rules, allow user to specify the form or group with the ability to force the form, or group, into Read-Only mode.
