This is possible, but not from this dialogue.
You first insert the clips as you show in your dialog.
Then you use the align clip function from the tool clip window, with these settings (after selecting the clips)
It would be even better, if we could enter the exact number of samples… (remember the request for showing the number of samples for plugin delay sometimes ago?)
At 192 kHz, 1ms is not good enough.
There are practical usecases, where we need an exact alignment of n samplepoints. This can not be done with the coarse integer ms.
