Multiple Kara interstitial entries

@Mohammad Is there way to add multiple interstitial entries in single Tiddler?

Yes, you need to use different tiddler to host the data.

<<interstitial tiddler:"aaa" showInput:"" focus:"yes" mode:"">>


<<interstitial tiddler:"bbb" showInput:"" focus:"yes" mode:"">>

Can we use same tiddler to host data? like by using fields or @@.block?

Alternatively my use case can be solve by using ‘current week’ in ‘tiddler’ parameter, I tried using ‘now’ macro but i have not managed to make it work.
