+Version 0.2.0 or later, subsections adding/overwriting are supported. About the case below, three `<store>` subsections are defined for `search.**` pattern.
+
+    <match service.*>
+      type forest
+      subtype copy
+      <template>
+        <store>
+          type file
+          path /path/to/copy1
+        </store>
+        <store>
+          type file
+          path /path/to/copy2
+        </store>
+      </template>
+      <case search.**>
+        <store>
+          type file
+          path /path/to/copy3
+        </store>
+      </case>
+    </match>
+
+Subsections with same arguments will be overwritten. See this example:
+
+    <match service.*>
+      type forest
+      subtype route
+      <template>
+        <route {search,admin}.a>
+          add_prefix first
+        </route>
+        <route {search,admin}.b>
+          add_prefix second
+        </route>
+        <route {search,admin}.c>
+          add_prefix third
+        </route>
+        <route {search,admin}.*>
+          add_prefix extra
+        </route>
+      </template>
+      <case admin.*>
+        <route {search,admin}.*>
+          add_prefix other
+        </route>
+      </case>
+    </match>
+
+In this case, `<route {search,admin}.*>` subsection will be overwritten to add prefix 'other' for tag `service.admin.*`.
