Cannot open spool files with the same DD name in different steps

[deltatager]

Describe the bug

After running a JCL with multiple steps containing the same DD names, you can only view one of the spool files with that DD name because the extension gives the same name to the local file.

The local file name is generated as ${spool.jobname}.${spool.jobid}.${spool.ddname}, meaning that two DD cards with the same name, in different steps, will result is the same file name being generated

When trying to open the second spool file with the same name, the first one is showed. It is very common to have many SYSPRINT DD in a single JCL.

To Reproduce

1. Run a JCL with at least two steps sending a DD with the same name to SYSOUT
   

2. Open the first SYSUT2 spool file

3. Open the second SYSUT2 spool file. The content of the first SYSUT2 will be shown, because they have the same local file name

Expected behavior

The content of the second spool file should be displayed, and the file names shoud be unique for each step
