Is their a way to import text from a variable/file and have swish apply effects to it?

Example: Make a blank text field with the wave effect applied to it. When new numbers/text appear in box... effect applies for that text. Of course, this would cause the file size to vary depending on the number of chars in the box, but that's ok?

I hope the SWiSH creaters read this message. This would be a fantastic upgrade!
