希望变换约束能支持不同属性之间的约束，例如位移控制缩放、X轴控制Y轴等。
实际上，增加这一功能已经在我们的路线图上了。:
Actually, adding that feature is already on our roadmap:

我们已经收到了许多这方面的请求，但由于一些游戏工具包不支持这一点，所以这相当困难。
We have received many requests for this, but it is quite difficult due to the fact that some game toolkits do not support this.
Spine编辑器的开发者Nate此前曾在此回复。:

此外，我的工作使用的版本是3.8，但我非常喜欢4.1的新曲线工具。4.1能够导出任意旧版本是个神奇的功能，但是我知道会丢失曲线。我在想，如果我使用4.1的时候，尽量不使用新的yx轴拆分等受影响的新功能，导出旧版本时能最大程度保留曲线的话，那就太完美了。
我们理解，如果能做到这一点是很理想的，但不幸的是，只对某些功能进行向前兼容是不可能的。请考虑为你的项目更新Spine版本。如果你在升级项目中的Spine运行时时遇到任何麻烦，我们将很乐意帮助你。
We understand that it would be ideal if such a thing could be done, but unfortunately it is not possible to have forward compatibility for only some functions. Please consider updating the Spine version for your project. If you are having any troubles upgrading the Spine runtime in your project, we would be happy to assist you.
