Prevent title tags on some pages

I realise that what I want is not possible through options currently, and that something similar has been asked before (eg the recent question entitled Bypass settings), but I would like to feed through my need for your consideration.

I have WP integrated with another system (TNG – a genealogical system), and all TNG pages come through to WP as (eg) TNG/xxx. WP, AIOSEO and every other system I have tried give just TNG as the title for such pages (and if allowed canonicalise them all to the same page). I have far more TNG pages than WP so my SEO needs are mostly to do with them.

I managed to tweak Suffusion (upto 4.4.7) to enable TNG pages to show the title I want and NOT to be canonicalised. But now in Suffusion 4.4.8 all SEO aspects have been removed and I cannot do it that way. I am told I now need to switch to a SEO plugin to do such things, but none seem able to do what I want out of the box.

TNG generates its own title tag, which is output after the WP/AIOSEO one so is ignored. All I think I need to do is to prevent WP/AIOSEO outputting a title tag for TNG pages. I can see an option for AIOSEO to not process certain pages, but a WP title tag is still output.

My questions are:
1. Could you consider putting in an option for preventing the writing of any title tag for a particular format of page (in my case above TNG/*), so that the title tag generated by TNG is the first one and takes effect.
2. Can you give me any pointers as to where I might be able to tweak the AIOSEO code to achieve this myself in the meantime?

Thanks – I hear good things about AIOSEO and, if I can resolve this major aspect, I look forward to exploring and using it more.
