[SalesForce] Unable to add time-dependent trigger to workflow rule

I have a workflow rule with a time-dependent trigger on it. It's been working fine for years. I now have a requirement to add an additional time-dependent trigger to the workflow rule.

I disabled the workflow rule, clicked edit, but the button "Add Time Trigger" is disabled. I went to my Sandbox environment to try and reproduce the issue, but I was able to add the second time trigger to that workflow rule.

How can I add an additional time trigger?

Time trigger button disabled

Edit: After RTFM, I found this:

You can't add or remove time triggers if the workflow rule is deactivated but has pending actions in the queue.

I certainly don't want to remove all of the pending actions; many of those are e-mails that need to be sent out to customers. Is my only way around this problem to create an identical (duplicate) workflow rule?

The issue was that there were actions in the queue. From the Salesforce docs:

You can't add or remove time triggers if the workflow rule is deactivated but has pending actions in the queue.
