Competitor adv consideration

[Emnlv]

How it is structured Robyn MMM, I think it desn't consider too much the competitor adv.

What I mean is that, since the adv of comp needs adstocked effect and forced to be negative, how this influence all of the other investments satuaration curve? For what I saw, competitor curve are included in the graph, whilst have not to be considered.

In conclusion, can be better to create another 3 vectors as: paid_media_comp_spends/vars/signs, where we can see effect on cannibalisation or volume/ROI erosion due to comp adv, including different graphs?

Thanks in advance!
