SwipeSpotlight 3.4 - Use with Group Layers

Hi,

I'm trying to use the SwipeSpotlight 3.4 widget on group layers. At the moment only the top level group layers are pulled through into the widget's drop down list, whereas ideally I would like the bottom level (ie actual data layers) to be used.

So, in the following example, currently the drop down list shows '5 Year Data' and '10 Year Data' whereas I really need it to show 'Layer 1, Layer 2, Layer 3...' etc.

> 5 Year Data
>> 100m Data
>>> Layer 1
>>> Layer 2
>> 500m Data
>>> Layer 3
>>> Layer 4

> 10 Year Data
>> 100m Data
>>> Layer 5
>>> Layer 6
>> 500m Data
>>> Layer 7
>>> Layer 8

(There are a lot of layers in the real webviewer, so listing them all out separately is not really a viable solution)

Are there any settings I can change to achieve this functionality, or is there a workaround of some description?

Many thanks!
Natalie
