Regarding how to setup a dsl file to make it on Library manager recognized as a new component.

I tried many times to register a dsl file of power component to my library in Design SparK PCB Ver11.0.2,

but it was unable to recognize as a new conpornent in the library manager.

This is refering a contents of following path.

However, it cannot import a dsl file because it was uanble to choose as dsl extension(Pull down menu) in Schematic Symbols tab of Library Manager.

In this case, how should I do setup this to import a dsl file in Lirabry Manager?

Best Regardfs,
