bulk edit records and run internal logic

bulk edit records and run internal logic

hi

there is few logics in manner "it this than that"
logics work well when i edit entry openning it one by one (via workflow "on add/edit - on success" , for custom field "on update/on user input")
but when i try bulk edit records - logic does not work. 

how can i turn on logic to work as programmed - for mass editing records via bulk edit?
