Is it possible to create a report, that can provide me with the JobNumbers of Orders that contain one or multiple products/services using filters?

My data can look like this:

Job# 1111
- OrderDetail1 - Sweeping

Job # 2222
- OrderDetail1 - Striping
- OrderDetail2 - Striping
- OrderDetail3 - Striping

Job # 3333
- OrderDetail1 - Asphalt
- OrderDetail2 - Striping
- OrderDetail3 - Sweeping

Here is what I started with, but I am getting redundant JobNumber records due to multiple matching ActivityTypes (Services) on each order.
If I filter to see all Striping Jobs, I will see multiple records for one Job where I only want to see one record per JobNumber:

JobNumber | Activity Type
2222 | Striping
2222 | Striping
2222 | Striping
3333 | Striping


Code:
SELECT
JobNumber, 
MastOps.ActivityType AS ActivityType
FROM dbo.[OrderDtl] OrdDtl
LEFT JOIN dbo.MASTOPS MastOps ON OrdDtl.MastOpsIdno = MastOps.MastOpsIdno
WHERE @FILTER_T:ActivityType@
