can syncLead update a known lead by the munchkin cookie ,and merge the anonymous lead's pageviews,Campaigns to the known lead ?
the more data transfer solution are as follows ：
1、mywebsite {cookie+pageviews,Campaigns} ------auto-----> marketo()
2、mywebsite {Email,firstname,... etc data} ---send-----> salesforce
3、mywebsite {cookie + Email }-----send(syncLead)----->marketo(syncLead)
4、salesforce{Email,firstname,... etc data} ---- send（ Marketo App）---->marketo
the steps above ,is this solution works?
