Yes — in **AutomationEdge Process Studio** there _are_ steps you can use to join two (or more) streams under different conditions — not only **Merge Join** :

### ✅ Available join-type steps in AutomationEdge

These are part of the **Joins plugin** :

**1️⃣ Merge Join**

- Joins two streams based on a **common key field** (Inner, Left Outer, Right Outer, Full Outer).

- Requires sorted keys.

**2️⃣ Multiway Merge Join**

- Allows joining **more than two streams** at once on a join condition.

- Useful when you need to combine multiple inputs in a single join step with INNER or FULL OUTER logic.

**3️⃣ Merge Rows (diff)**

- If your condition is about **comparing and merging rows** (determining changed/new/identical rows) rather than a straight relational join, this step can merge two streams and emit flags.

**4️⃣ Join Rows (Cartesian product)**

- If you want to join streams **without a key** or under condition logic you define manually, you can use a Cartesian product join combined with conditions in a filter step afterward.
