i have already mapped the required variables in Tealium mapping toolbox (for option A), only one issue noticed when pass "impression_cm_sp" or "impression_cm_cr" values in array to trigger multiple impressions.
impression_cm_sp : ["contextualnav-_-bittybaby-_-seatedbabyandbook", "a-_-b-_-c", "x-_-a-_-b"]
it triggers only one impression in above example, but we have passed 3 site promotion impression.
Department*Initiative*Link (cm_sp):"contextualnav-_-bittybaby-_-seatedbabyandbook", a-_-b-_-c, x-_-a-_-b"
We would need option A in some instances where we are not passing any link in banner/image but tracking impression for that banner/image.
Option 2 is easy to use but not sure if this can be used if need only impression? image/banner (without any url).
