Nauld1,
Good afternoon! I think you should be able to create a form that lists the parameters you wish to change and then invoke a simple rule to launch that form. I could get this method to work beautifully when saving the document, but was having trouble getting it to work properly when opening the document. Therefore, I created a Master_Rule that launched the form rule when the document either opened or was saved. I tested it out and this also worked for a Save As. Instead of lots of screen captures, I am simply including a sample part that has the rules, the conditions and the forms that you can use as an example. If you are unfamiliar with setting the Rule Triggers, I have included a screenshot for those settings. Otherwise just refer to the sample part. If you have any questions, please do not hesitate to contact me. Hope this helps and have a most blessed night!
