Loadvars at a specific frame

Is there any way to specify which frame to load variables (for a text box) in the text file? I mean… With no key frames… Or something.

For example,


[textfile.txt]
70, thistext = hello

Would put ‘hello’ in a textbox at frame 70.

I want to do this to make it as simple as possible to enter subtitles into a movie I’m making… I know how to load text from a txt file, so don’t worry about that.

Thanks.
