Programmatically change binding to another key

[Paliverse]

Hello, I love this project you've built for localization, it works perfectly with static text, but i would like to know how can i manually change the binding from xaml programmatically to another key from file. For example, i have a label that i update with different texts, i would like to be able to assign that label binding key1 and programmatically change it to key2 so that i can have different strings for that label using different keys. I'm new to wpf and would appreciate your help with this issue!
