OK, Thanks. I was hoping that I was not going to need to do that.
I am not the only one looking for this functionality as there is a ton of stuff re indesign on the same subject. I did manage to do it using a script, but the result was not ideal.
If Affinity want to attract some market share of photobook makers, then templates for one click books would be really good. Lightroom, photos etc facilitate this but fall down on the publishing tool power and inability to make larger PDF docs for instance. Not looked at the Affinity photo programme.
Affinity seems more friendly, and armed with the info you have given me, I will start clicking. 😀
Thanks again for your help.
