Merged PR 4483: Adding targets (to be revised). Allows multi-year last-date computation

# Description

Changes:
* Adds template for targets -> These need to be revised
* Adds comparison of values vs. targets
* Allows for multi-year last date computation (allowing multiple years to be selected, not just the last one)
