angularjs - Clever bulk update in Angular $resource -

here's i'd achieve:

say have todo list , following changes:

• mark complete task 1
• change name of task 2
• mark complete task 2
• change name of task 1

at present, system can achieve firing 4 http queries. there way angular can sync app server, every 20 seconds, able notice when change has been done on same item, , group changes same query.

the clever bulk update like:

• update task 1, set complete=true, name= new name
• update task 2, set complete=true, name= new name

has ever tried this? idea way should search find out more info kind of workflow?
