You don't need multiple screening questionnaires to handle every nuance of screening.

Listing Groups can be used to trigger any screening question on any Pre-Showing Questionnaire. This means a single screening questionnaire can dynamically adjusts to different listings so individual questions are automatically included or excluded. 

Adding a conditional screening question is easy:

1. Go to the Showing Qualification Settings page.
2. Under each question, look for the IF toggle.
3. Click it.
4. Then you’ll see a listing group selector.
5. Add one or more listing groups and the question appears only when needed. 

And it gets even more powerful when you automate the listing group assignment for imported listings. (See the Listing Groups article for more details on that.)

Conditional Screening Questions are not available in ShowMojo CLASSIC.
