Marek,

I think that a GlobalVariable of type java.util.Map would be useful for you.

I have made a project “[KatalonDiscussion9854](https://github.com/kazurayam/KatalonDiscussion9854)” to demonstrate my proposal. You can download the zip file from [Releases](https://github.com/kazurayam/KatalonDiscussion9854/releases) page.

I would copy & paste the README here.  
---------------------------

# How to run the demo

1. start your Katalon Studio, open this project
2. please note that a Profile `default` defines a GlobalVariable named `MEMORY` of type `java.util.Map`.
3. select `Test Suites/TS0` and run it

# Processing

1. `GlobalVariable.MEMORY` is initialized with values: `['A':'a', 'B':'b', 'C':'c', 'D':'d', 'E':'e']`
2. Test Suite `TS0` execute a series of test cases: `TC1`, `TC2`, `TC3`.
3. Each test cases prints `MEMORY`, and update it.

# Code

The source of test cases is very simple. For example, `TC1` is as simple as this:

```auto
import internal.GlobalVariable as GlobalVariableMap memory = (Map)GlobalVariable.MEMORY
CustomKeywords.'my.MemoryManager.retrieve'(memory) # retrieve memory
memory.put('A', "TC1 said hello")                 

```

# Output

TC1 prints the MEMORY, as follows:

```auto
key=A,value=akey=B,value=b
key=C,value=c
key=D,value=d
key=E,value=e

```

TC2 prints the MEMORY, as follows:

```auto
key=A,value=TC1 said hellokey=B,value=b
key=C,value=c
key=D,value=d
key=E,value=e

```

TC3 prints the MEMORY, as follows:

```auto
key=A,value=TC1 said hellokey=B,value=TC2 said welcome
key=C,value=c
key=D,value=d
key=E,value=e

```

TC4 prints the MEMORY, as follows:

```auto
key=A,value=TC1 said hellokey=B,value=TC2 said welcome
key=C,value=TC3 said goodbye
key=D,value=d
key=E,value=e

```

Please note that the `GlobalVariable.MEMORY` is shared by test cases and updated mutually by them.

# Conclusion

Each test cases declares a single variable `Map memory` which contains multiple key=value pairs. This reduces need to type variable names repeatedly in each test cases.
