multisite events search

Hello,

with shortcode I can show events list from all subsites with the blog=x attribute

I can also put a search form with the event_search_form shortcode, but this form redirects to the default events page, witch does not have (AFAIK) any way to configure the blog attribute. Therefore I cannot search on all events as I want to. (the search is restricted on a subset of the events that were presented, which is strange for the user)

Is there a way to, either make the search form uses my custom event list (shown with a shortcode); or configure the default event list page’s blog attribute ?

NB: I already tried to set the events permalink setting to my own events list, but this did not worked as intended (i.e. the search was not performed, the list was rendered as defined by the shortcode I wrote)

Regards,
