Can visit_standard_length be set per website?

As far as I understand

 visit_standard_length

is a global setting. Is there a way to set the visit duration separately for each website tracked? Thanks.

p.s.: I know there is at least one same topic. I was wondering if there is anything new about it.

It is not possible to change per website at this stage. You can sponsor this feature, by contacting http://piwik.org/consulting/
