How to continue training a Lora that was trained in CivtAi?

I trained a Lora using the trainer in Civai. But I want to improve it. How can I continue to train the current trained model?

I think this function still not included, because train a lora in Civitai just began and in Alpha.

I don't think you can, there is no such option available currently. You need to start a new training with more epochs/repeats/steps.
