In Syside v0.11 there may be!
With Syside v0.11 we are introducing syside.query module that contains higher level API, and one function specializations could probably be used to do what you want.
You can get the pre-release to try out as described here: Syside v0.11.0-rc.1: try out new features earlier
I don’t recommend relying for this in production yet, as we have found some bugs in the pre-release that will be fixed for the final 0.11.0, so we don’t want you to accidentally become reliant on some of those hidden bugs.
