Hello my Amelia friends, it's me again. :)

I have customized Amelia to work for our pet-services business and continue to be amazed at how powerful and customizable it is. I have discovered a couple of features that don't work as intended, and I have tickets out about those. This email is to see if perhaps there is another element of flexibility I am missing.

I have a number of services across multiple categories. One of the categories I have is an admin-only collection of services and packages, that I don't want to display except to admins. But otherwise, I want the user to be able to choose from the various other categories of services. 

I am using the shortcode [ameliastepbooking] to display the booking form. [ameliastepbooking category=1] Doesn't work for me because i do want the customer to be able to pick from a variety of categories. What I really want is to be able to display [ameliastepbooking category=1,2,3,4] but that doesn't seem to work.

I also use Ultimate Member which allows me to restrict access to content based on user level. In this way I can display a different booking form for my admins than my customer. But for customers I need to display every category EXCEPT 1. It does me no good to display either ALL categories or just 1 category. Is it possible to display multiple categories but not all categories in the new step booking form?
