Automatically Inject code into Closed Caption File

Premiere Pro has been very good at creating fairly accurate closed captioning for the projects that I've been editing. One problem I've run into is that for our on-air system to play the CC, there must be a specific line of code at the beginning of each file. 

Here is an example of what I'm talking about

=================

#LGXFMT=RU3

<There's a hard return here>

1
00:00:06,973 --> 00:00:09,440
The life of the modern-day kitten

========================

Is there a way to have Premier Pro automatically insert the code at the beginning when it creates the SRT file or begins transcribing a timeline?
