Is it possible to offer Plesk aplications within Plesk Domain hosting plans without adding those applications to OBAS first?
In other words, is it possible to provision hosting plans that allow permission "Access to Application Catalog" and do not automatically check "Provide only applications that I select" option?
That is not possible at present. Feature request PBAS-27662 was submitted and will be considered to be implemented in future OBAS releases.
