Custom code email with image and text area drag and drop functionality

Hi There,

I am working on a custom coded email template, so far I can make some areas have the Klaviyo drag and drop editable regions but not all. If the area is just text I add the code to the <td>

<td align="center" data-klaviyo-region="true" data-klaviyo-region-width-pixels="600">

and then wrap the inner content in a 

<div class="klaviyo-block klaviyo-text-block">

and it works fine. Same for image, with the other class.

But some areas have text and image. When I add the text class in the div the image areas are not editable in the same way as if it were a just an image area. If I add both classes it strips the text out.

Any way to have a combo area?
