Hello Legal & Economic Press, s.r.o,

I am really sorry for the delay of this reply as it is a weekend for us here.

Unfortunately that was not possible.

But we do have Easyblog Biography custom field available in current system. You can download from here http://stackideas.com/apps/item/44-easyblog-biography and install in your Easysocial > application > install area.

What this custom field task is integrate with Easyblog profile "short biography " field. Check my screenshot below.

Hope this help.
