It would be excellent to have the possibility of creating global variables which can be accessed from any topic. For example, if I ask the customer for the email, know in all the topics which is the client's email without having to ask again
Please comment on this post and share with us your scenarios around "global variables". If you have ideas on how you'd like to use it in the product, please share it with us too.
In my case, you could substitute global for persistent. In many scenarios we have to ask the same question over again as we cannot pass info across topics. For example, I may need an email address to create a support case, but I also need one to send a report. Currently, I have to ask twice. On top of that, in some cases I may want the users alias, in others their email address, but with either one of those, I can generally extrapolate the other and should be able to simply apply it to a variable that was never prompted to the user.
They alredy says that the Global Variables will be launch in March 20, here you can see what feature will coming: https://docs.microsoft.com/pt-br/power-platform-release-plan/2019wave2/power-virtual-agents/planned-...
