Add more positions to apps on profil page

Hello,

i have jreviews installed on my web site (amazing by the way), it come with some apps for easysocial, for example to show the listings on profil pages, by defaut there is three positions :

canvas - sidebar at the end, sidebar at the begining and above stream.

can we add under stream position ?
we show profil information by defaut on our profils and it would be great to show listings just under those profil info !

regards
