How can I make seitan sausages from a homemade seitan block?

So far I have made washed flour seitan blocks from wheat flour and seitan sausages from a seitan flour and chickpeas mixture.

I would like to use my homemade seitan block instead of the seitan flour for my sausages, as for me the wheat flour is easier to get than the seitan flour.

I have tried to roll the unsteamed seitan block into a sausage shape, but the seitan isn’t moldable enough to do that. (I have found this related question, but I don’t think that the answers are applicable to using a seitan block as the basis for the sausages, as the homemade seitan block doesn't even get close to anything that resembles a sausage shape :) and I never had any problems rolling my sausages using the mixture from seitan flour.)

When I tried to steam the seitan block as usual and grind it afterwards, the mixture wasn’t binding and the sausages were not holding their shape.

Is there a way to use homemade seitan blocks as a replacement for seitan flour to make seitan sausages? If yes, what would I need to do/change in order to do this?
