Add a option to upload multiple epochs of the same model/lora

Currently the "versions" feature seems to be intended for updates in the models/loras but there is not an easy way to upload multiple epochs of the same lora, to do this we have to create several versions and copy-paste the same info on them (since its the same lora but just with more/less training), which doesn't seem right for the same model, it would be nice to have a feature that allows you to specifically upload different epochs of the same lora/model, because early/late epochs have weaker/stronger effects and its nice to add more options for people to choose from, which will also retain the apparent purpose of the "versions" feature (actual different versions with different parameters that behaves differently)
