Help with nbt item tags

Hello! I would like to know how and if it is possible to interact with vanilla item tags through Mcreator procedures? 

As an example: 

We have an item issued by the command: "/give @a cobblestone[attribute_modifiers={modifiers:[{type:"generic.attack_knockback",amount:0.7,name:"generic.attack_knockback",uuid:[I;-124520,5888,142233,-11776],operation:add_value}]}]" 

Can I give a similar vanilla nbt attribute tag to my custom item?

P.S. I used a translator
