问是否可以在主Vue实例上的方法中添加/删除组件的道具？

EN

Vue.component('v-button', {
    props: ['loading'],
    template: '<button class="btn btn-info"> <span v-if="loading != undefined">Loading...</span> <span v-else><slot></slot></span> </button>'
});

new Vue({
    el: '#app',
    components: ['v-button'],
    methods: {
        niceMethod: function(argument) {
        console.log(argument);
        // Considering that I will have a large amount of v-buttons:
        // Is it possible to do something here to add or remove the prop "loading" ONLY on the v-button I've clicked?
    }
  }
})

<div id="app" class="p-5">
  <p><v-button @click.native="niceMethod('testing!')">Test</v-button></p>
  <p><v-button @click.native="niceMethod('hello!')">Hello</v-button></p>
  <p><v-button @click.native="niceMethod('vue!')">Vuejs</v-button></p>
</div>
