Add spend for filter
If start is the same as end it spend would created for a single day. If start and end are different it would take value and divide it by number of days between start and end, then each single day it would be have a proportional spend value. For example: start=2024-12-01, end=2024-12-05, value=1000 it would result that each day would have 200 as spent amount.
