I don't think this requires special support from the convolution
engine - it's jsut an application of it.
Suppose you have the start of a reverb response:
(imagine the y-scale is logarithmic)

and you feed back the output with the correct gain and delay,
then the result will be a complete exponential decay.
This is too simplistic, and will probably give a 'echo' like
character to the reverb, but that's the principle. It should
be applied to the first part of the reverb 'tail' only, not
the early reflections. But you only need a short convolution.
