New Tab in Existing Lister vs. New Lister

I'm using DOpus with On1 Photo Raw, a photo editing and organizing tool. Photo Raw has a batch export function that takes all selected photos, reformats them to a desired size, and writes them to a new folder. I have the batch job set to create a subfolder in the folder where the pictures reside called Export.

If I have created the subfolder Export already, and have it open in the current tab in a Lister, the subfolder tab is updated perfectly.

But if I have not created the subfolder or do not currently have the subfolder open in a current tab, DOpus opens an entirely new Lister with a tab showing the new subfolder. I would prefer DOpus just open a new tab in the current lister and display it. I've looked through all the Lister preferences and can't find one that does the trick.

Reason this is desirable for me: I keep several tabs open in my Lister all the time. One is a folder of flac tracks with about 7,000 songs. It has columns such as Channels that cause each file to be read, taking quite a while.

Any suggestions?

Thanks!

Thank You! I missed the Explorer Replacement section's "Open a new Tab instead of a new window" That did the trick.
