title: Selected primitives are incompatible with Koalas EntitySets: time_since_previous, avg_time_between, trend, avg_time_between, trend
body: <p>I am using featuretools 0.20.0 and koalas 1.3.0.</p>
  <h1>create feature matrix for all customers</h1>
  <p>feature_matrix_cust, feature_defs = ft.dfs(
  enter code here`entityset=es4,
  target_entity=&quot;customers_ks&quot;,
  agg_primitives=[&quot;count&quot;, &quot;avg_time_between&quot;, &quot;num_unique&quot;, &quot;trend&quot;],
  where_primitives=[&quot;count&quot;, &quot;avg_time_between&quot;,&quot;num_unique&quot;, &quot;trend&quot;],
  trans_primitives=[&quot;time_since_previous&quot;]
  )</p>
  <p>I got error below:
  ValueError: Selected primitives are incompatible with Koalas EntitySets: time_since_previous, avg_time_between, trend, avg_time_between, trend</p>
  <p>Will featuretools support those primitives for Koalas in the near future? Is there anyway to handle those primitives with current featuretools and Koalas version?</p>
