Prompt user before adding case to a queue based on multiple fields

Hi All,

I was wondering how and in what way the following requirement can be achieved.

On my Case entity form I have the below fields:

"Case Type" as an option set field.

"Case Disposition" also as an option set.

Currently users select case type and case dispositions, then in the top toolbar select "Add to Queue".

Is there a way to prompt the user after he hits "add to queue" that his case disposition isn't matching the predefined schema.

For example:

If the case type = A1 or A2 or A3 or A4 or A5

And case disposition does NOT = B1 or B2 or B3 or B4

Prompt the user: "A correct disposition must be set"

And Do NOT transfer the case to the requested queue.

I'm not experienced with writing plugins.  Can this be achieved with js?

Or is there any free plugins/solutions that can help me create this functionality.

Thank you.
