How do I export a document 50 times with different text for each in 1 text box (e.g CDA0214 - M)?

I have a document which I need to export 50 times with the same text frame apart from the last character (e.g CDA0214 - M). Is there a script which will make this process quicker as I need to do this with every brochure every day. Thank you in advance.
