Conflict with shortcode from Formidable Forms

I’m using the Custom Content Shortcode plugin for a site which also uses the formidable forms plugin (https://formidableforms.com/).

I need to use the [if category=abc] shortcodes Custom Content Shortcode provides in the formidable forms submit message. The problem is that formidable forms also uses the [if] shortcode for its own conditional display.

Is there a way to allow both shortcodes to work?
