@ServiceAc1 can you add more detail.
A dashboard has no info, you're probably talking about reports.
Sounds like you have 2 reports, and you'd like to combine the data sets by combining the report filters.
In general:
condition A
condition B
condition C
OR:1:condition D
OR:2:condition G
If the OR:1 or OR:2 has multiple parameters try
OR:1:AND:1:condition D
OR:1:AND:1:condition E
OR:1:AND:1:condition F
OR:2:AND:1:condition G
OR:2:AND:1:condition H
OR:2:AND:1:condition J
