We do this very thing with most of our components needing thermal attachment. We inject the material through a hole in the board using a syringe. We use a thermally conductive polyurethane and it has a working life of 2 hours. It will cure at room temp. (24 hrs) or 30 minutes at 100 deg.

There is a hole through the boards to allow some material to flow through, but the adhesive must NOT be electrically conductive. We've tried the Output 384 by Loctite, but it hardens too fast and doesn't flow enough. For technical reasons, we cannot apply the adhesive before the boards is assembled. Any ideas would be welcome.
