You cannot filter directly on the probes but you can include the list of 
probes participating in the measurement:

https://atlas.ripe.net/api/v2/measurements/29786041/?optional_fields=probes 
<https://atlas.ripe.net/api/v2/measurements/29786041/?optional_fields=probes>

You can then iterate over this key to find if the probes you're looking 
for are included and get only those results with something like this:

https://atlas.ripe.net/api/v2/measurements/29786041/results/?probe_ids=6945 
<https://atlas.ripe.net/api/v2/measurements/29786041/results/?probe_ids=6945>

Hope this helps,

Cheers,
Johan
