SLT transformation scenarios

Hi Experts,

Needed your inputs on below two scenarios-

scenario 1 - As we are aware about the SLT triggers that are present for insert, change, delete scenarios.

table A  ---> table B (replication only done when any rows are inserted in table A)

table A----> table C (replication only done when a field in table A say 'qty' is modified)

Can we have  replication restricted on triggers?

scenario 2- one row from source flowing in as many rows into target table

table A has below structure

object1  value1   value2

pen           10       20

so now when i replicate table A to table B, it should get populated as follows-

table B has the new structure as below

object1   value1

pen        10

pen         20

I am aware of transformations wherein additional columns can be added with additional logic.

But is it possible to add additional rows based on one source row?
