Yes. With the Transfer to Workflow step, you can automatically move subscribers from your keyword workflow to your automated one.
Scroll to the bottom of your keyword workflow and select Add Step > Transfer to Workflow.
Adding this step will remove the subscribers from your keyword workflow at your chosen point and enter them into the selected automated workflow.
For example, say you've set up an automated workflow to follow up with visitors who fill out a paper connect card. You have 5-7 follow-up texts that you send them over the course of a few weeks reminding them of service times and encouraging them to get plugged in.
A few months down the road, you decide you want to create a keyword to let your visitors connect with you via text instead of using the paper form. Instead of creating a completely new workflow, simply create your keyword and choose the Transfer to Workflow step to send them to your existing visitor follow-up workflow.
Note: If you only want to move some people to an automated workflow, check out branches. With branches, you can transfer specific subscribers while keeping the other subscribers in your existing workflow.
