@raamdev I am seeing a minor problem in this PR. I'll come back to this shortly and explain. It's nothing that Kristine introduced, but it looks like there is a minor bug in the existing release and we can knock that out as part of the work being done on this PR. More to come shortly...

@jaswsinc That has been updated. 👍 6ac79e9

[jaswrks]

@kristineds Perfect. Thanks!

@raamdev Kristine's last commit improves this PR and also resolves this bug.

[raamdev]

@jaswsinc I'm not seeing that this is configurable (as discussed here). Can we at least make the schedule filterable?

[raamdev]

@jaswsinc Sorry, I jumped the gun. :-) I didn't see that Step 2 had not yet been completed.

[raamdev]

Oh, it has been finished, but in a separate PR: #180

[raamdev]

Merged. Thank you, @kristineds! :-)
